SPECIFICATION forming part of Letters Patent No. 752,59*?, dated February 16, 1904, i

Application led October 3, 1902. Serial N0. 125,794. (No model.)

To all whom it may concern;

Be it known that I, JOHN ScHrEs, a citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have made certain new and useful Improvements in Glass Blowing and Finishing Machines, of which the following is a specification.

My invention is a combined blowing and finishing machine designed to take the bottle as it is delivered from the press-molds of an ordinary glass-machine to finish the mouth thereof and to produce an internal groove within the neck of the bottle at one operation; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a sectional elevation of a machine embodying my invention, parts being broken away. Fig. 2 is a detail elevation taken in the direction of the arrow 2 in Fig. l. Fig. 3 is a side elevation of the pressing and blowing head, the upper portions of the levers being broken away. Fig. 4 is a vertical longitudinal section of the blowing and finishing head, the levers being partly broken away. Figs. 5 and 6 are detail views of the grooving-plates. Fig. 7 is a detail perspective view of the jam-nut. Fig. 8 is a perspective view of the main nut. Fig. 9 is a perspective view of the base-ring. Fig. l0 is a perspective view of the body portion of the head and the pins for pivoting the levers. Figs. 1l and 12 are detail views of the levers. Fig. 13 is a detail perspective view of the former, and Figs. 14 and 15 are perspective views of the grooving-plates.

By my invention I provide a blowing and finishing' head for application to the unfinished bottle or jar for iinishing the lip of the same and for producing' the circumferential groove within the neck of the jar. To this end I provide a suitable framing in which is journaled at A the drive-shaft A, to which power may be communicated in any suitable manner, and this shaft A is provided with a beveled gear A2, which meshes with abeveled gear B, which is keyed to the main shaft O, so the latter can move longitudinally to a limited extent through the gear B. This main shaft C is the air-supply pipe through which air is communicated to the head presently described, and the shaft C is connected by the coupling C to the valve-section D, provided with a valve whose stem Dl is provided with the handlearm D2, which rests in abarE, secured at E to the framing, so the tube O as it moves up will tend to close the valve and as it lowers'will cause the valve to open by the bearing of its handle-arm D2 on the bar E, which is connected with the framing. I thus provide in connection with the sliding tube a valve and an abutment on the frame for engagement by a part connected with the valve, so that vthe valve will be positively opened as the tubular shaft descends to operative position and will be permitted to close as the shaft rises from said position, the shaft being operated by the means presently described. At its lower end the tube O carries the blowing and finishing head F, which is of a special construction, as best shown in Figs. Sto l5, inclusive, and as shown in operative position in Fig. l. As shown, the head F is composed of a body portion G, (see Fig. 10,) a base-ring H, (see Fig. 9,) a main nut I, (see Fig. 8,) ajam-nut J, (see Fig. 7,) a former K, (see Fig. 13,) the grooving-plates L, (see Figs. 5, 6, 14, and 15,) and the levers M (see Figs. 11 and l2) for operating the grooving-plates, as will be presently described. In Figs. 7 to 15, inclusive, Ishow the several parts of the former detached, while in Figs. 3 and l I show the parts assembled. The body portion G is provided with a centrally-threaded opening g and has in its under side a groove r/ to form the lip of the jar. At its lower edge the body portion has the laterally-projecting flange G and is provided at its top with the eXternally-tlneaded portion G2, on which are threaded the nuts I and J, as presently described. The body is also provided withthe opposite longitudinal openings g2, which extend through it from top to bottom and appear as slots in the parts of the body portions above the flange G. The levers M are pivoted at M by means of pins m within the openings 'g2 and project at their lower ends below the bodyportion and lit at said ends at M2 in openings L in the groovingplates L, so the levers as they are rocked at their upper ends in and out will cause the grooving-plates L to project and be withdrawn so they will protrude in one position beyond the outer edge of the former K in producing the grooves in the jar-necks, as shownY in Fig. l, and will in the other position be retracted to form no projection beyond the outer face of the former K. At their upper ends the levers M project considerably above the head F and are engaged at their ends M3 by the operating device presently described, said ends M3 being preferably turned slightly, as shown in Figs. 1l and l2.

The former K is provided with the upwardly-facing shoulder K', upon which rest and operate the plates L, as above, the said shoulder K having a projecting threaded tenori K2, which journals in the lower end of the threaded opening g of the body portion G. The former is provided at the base of the tenon K2 with a narrow rib K3, which stops the former K in position to provide proper space for the operation of .the grooving plates L. The former K is tapered slightly to Jfacilitate its entrance into the jarneck and is shaped to conform to the finished jar-neck and is provided with an-air-passage through which air is supplied from the shaft C, and discharges at It" into the jar being iinished. The head K thus operates to supply air to the jar in'blowing and finishing the same, to form the internal surface of the jar-neck, and to produce therein by means of the plates L the internal annular groove desired. In operation the former is practically a portion of the body G and turns therewith in forming and grooving the neck of the jar,

the body portion resting upon the mouth ofA the jar and producing by this groove g the lip of the jar as desired. It will be'understood that this body operates within a ring, which may bear upon the mold, serving as a base for the head and as a support for the jar to be finished. The ring, as shown in Figs. 4 and 9, may preferably be formed with a ball-race H in its upper face and have its bore rabbeted at H to rest upon the lateral iiange G of the body G. The main nut I threads on the portion G2 of the body G down toward the base-ring H, balls N being arranged between the main nut and the base ring, as shown in Fig. 4. It may be preferred to provide ball-races in both the base-ring and the main nut, as shown, and when the nut I has been adjusted on the threaded portion of the body G to the desired position it may be secured in such position by the jam-nut J, turning down on the portion G2 and jamming in connection with the nut I to lock the latter in the desired position. I have shown the nuts I and K as provided in their peripheries with notches for engagement by a wrench and in their bores or central openings with notches 2 and 3, so the nuts I andJ can be slipped over the levers M in assembling the parts.

As best shown in Figs. 5 and 6, the groove ing-plates L are rounded on their o uter edges and also at their ends at L2, so they will then operate properly in the soft glass in the use of the invention. p

When the parts are assembled as shown in Figs. 3 and 4, it will be noticed the body can revolve within the base-ring, carrying with it the formerK and the nuts I and J, the nut I rolling on the balls N and the base-ring H being arranged to bear upon the mold O, in which the jar is held, as shown in Fig. 1. Manifestly this mold O can be made in sections to facilitate the insertion and the re moval of the jar., and when the parts are assembled as shown at Fig. 4 the air is snp-v plied from the tube C directly to the former K and passes thence into the jar being finished. rIhe levers M extend upwardly along the opposite side of the tube C and are pressed normally outward at their upper ends by springs P, so the lower ends of the levers are normally retracted and retain the grooving-plates L in the retracted position shown in Fig. 4. In order to raise the tube C and to permit it to lower and also to contract the `upper ends of the levers M after the head has been lowered by the lowering of the tube C, I provide on the tube C a shoulder or projection C2, below which is supported the lever-compressor Q, which is in the form ofa iiaring hood, converging upwardly and operating at its lower face upon the upper ends of the levers M in such mannertas to contract the same when the compressor Q is lowered into engagement with the said levers. This compressor is slidable upon the tube C and may be adjusted from the position shown in Fig. l, wherein it compresses the upper ends of the levers M upwardly to release said levers and then to move into engagement with the projection C2 on the shaft C in such manner as to raise the shaft C-and lift the headF out of the jar after the grooving-plates L have been permitted to adjust to the position shown in Fig. 4. The compressor is operated from a treadle or other lever R through a connecting-rod S, which is operated on by a spring T in such manner as to hold the compressor Q normally in elevated position, and the rod S is connected with the compressor Q by means of a ring or collar S', operating in a groove Q in the compressor, so the latter when it is adjusted into engagement with the upper ends of the levers M may revolve with the said levers in the operation of the head F in blowing and finishing the bottle.

From the foregoing it will be understood that the shaft C is hollow and receives air from a suitable supply and that such shaft may move longitudinally through the beveled gear B, by which it is turned, as such gear B is keyed to the shaft C, as before described. If the parts be in the position shown in Fig. 1 and the jar has been finished, pressure on IOO IIO

' to admit air.

the lever R may be released, and the compressor Q will move upward, first releasing the levers M, which will be spread at their upper ends by the springs P and retracted at their lower ends in such manner as to adjust the grooving-plates L out of the groove which they have produced in the neck of the jar. Further upward movement of the compressor Q will cause it to engage beneath the projection C2 of the shaft C, and the shaft C will then be lifted, raising the head F out of the jar, which can then be removed and another placed in the mold C for the finishing operation. As the shaft C moves upward to lift the head F the handle D2 of its valve will as the shaft C rises operate to close the valve and shut oif the supply of air to the pipe C when the head F is out of the jar to be finished. After another jar has been inserted in the mold the lever R may be operated to force the compressor downward. As such compressor lowers, the weight of the head and of the shaft C will carry such parts down until the head rests upon the mold and in contact with the jar to be finished. Further movement of the lever R will cause the compressor to move down into engagement with the levers M, compress the upper ends of said levers, and cause the plates L to be forced downward to produce the groove in the neck of the jar. It will be understood that during all this operation the shaft C and the head F are being constantly revolved and that as the head is pressed into contact with the mold O the base-ring will bear upon the said mold, and the body portion of the head andthe parts immediately connected therewith may turn within the basering in the operation of finishing the jar. It will also be understood that as the tubular shaft C moves downward the valve-handle D2 will engage with the abutment E on the frame of the machine, and the valve will be opened I thus provide a machine by whichthe jar is blown and finished at the one operation and which involves no complicated construction of parts which would likely get out of order in the use of the machine.
